13 # Darren Critchley February 2003 - I added the multiple external access rules for each port forward
14 # A couple of things to remember when reading the code
15 # There are two kinds of records in the config file, those with a number in the first field, and then 0,
16 # these are port forward rules, these records will have a 0 or 0.0.0.0 in position 9 (ORIG_IP)
17 # If there is a 0, it means that there are external access rules, otherwise the port is open to ALL.
18 # The second type of record is a number followed by a number which indicates that it is an external access
19 # rule. The first number indicates which Portfw rule it belongs to, and the second is just a unique key.
